The vulnerability (CWE-125) in multiple Qualcomm chipsets arises due to improper bounds checking in firmware handling memory operations. An attacker can trigger an out-of-bounds read by sending crafted data to affected components (e.g., Wi-Fi, modem, or DSP firmware), potentially leaking sensitive information or causing denial-of-service. The flaw exists in memory access functions where input validation is missing, allowing read operations beyond allocated buffer limits. Exploitation could occur remotely via malicious network packets or locally via privileged processes.
